Aircraft Accident/Incident Report

Maple Lake, Minnesota 55358
Saturday, July 17, 1999 17:23 CDT

NTSB Narrative Summary Released at Completion of Accident

The float plane was flown from one lake to another where the pilot picked up a passenger. The pilot reported that during the second take off, he had pitch problems during the climb and that the nose always wanted to pitch up. At approximately 50 to 100 feet, the airplane started turning to the left and the nose pitched down, followed by a crash in the lake. The pilot stated that he did not do a weight and balance or a performance calculation prior to takeoff. The airplane was found with the elevator trim in the full nose down position. The weight and balance of the airplane dated May 12, 1973, recorded the maximum gross weight of the airplane as 1,294 pounds. The approximate weight of the airplane during the accident flight totaled 1420 pounds.

NTSB Probable Cause Narrative

The pilot's inadequate preflight planning that resulted in exceeding the maximum gross weight of the airplane and the subsequent inadvertent aerodynamic stall.
